Struct ArdConfig 

pub struct ArdConfig {
    pub alpha_init: f64,
    pub beta_init: f64,
    pub max_iter: usize,
    pub tol: f64,
    pub update_beta: bool,
}

Configuration for the BLR+ARD EM fitting loop.

Defaults match the Python reference: alpha_init=1.0, beta_init=1.0, max_iter=100, tol=1e-5, update_beta=true.

Fields

alpha_init: f64

Initial value for all ARD precision hyperparameters α_j.

beta_init: f64

Initial noise precision β = 1/σ².

max_iter: usize

Maximum number of EM iterations.

tol: f64

Convergence tolerance on the period-2 log-evidence delta.

update_beta: bool

Whether to update β during the M-step.
